摘要： An infusion pump (e.g., an electrokinetic infusion pump) includes an infusion pump module and an engine that can drive a moveable piston non-mechanically. In addition, the infusion pump module includes a position detector configured for sensing a dispensing state of the infusion pump module. Such information can be utilized in a control scheme to control fluid displacement within and out of the pump.

摘要： Systems and methods of detecting occlusions and fluid-loss conditions (e.g., disconnects and/or leakages) in an infusion pump are discussed. For example, electrokinetic infusion pumps may develop an occlusion in the fluid flow path, which can disrupt control of fluid dispersed from the pump. As well, an infusion set disconnect can also result in a fluid-loss that can be disruptive. Such disruptions can be troublesome to systems that control the infusion pump, such as closed loop controllers. Accordingly, systems and methods described herein can be used to detect such occlusions and fluid-loss conditions during infusion pump operation. For example, a position sensor can be used to monitor fluid flow from the infusion pump, with the measurement being compared with an expected value to detect an occlusion or fluid-loss condition. Other algorithms for utilizing the position sensor are also described.
摘要翻译：讨论了检测输液泵中的闭塞和液体流失状况（例如，断开和/或泄漏）的系统和方法。例如，电动输液泵可能在流体流动路径中形成阻塞，这可能破坏从泵分散的流体的控制。同样，输液器断开连接也会导致液体损失，这可能是破坏性的。对于控制输液泵的系统而言，这种中断可能会很麻烦，例如闭环控制器。相应地，本文描述的系统和方法可用于在输注泵操作期间检测这种闭塞和流体损失状况。例如，可以使用位置传感器来监测来自输液泵的流体流量，将测量值与期望值进行比较以检测堵塞或流体损失状况。还描述了用于利用位置传感器的其他算法。

摘要： A microfluidic chip (10) formed with multiple fluid channels (12) terminating at a tapered electrospray ionization tip (14) for mass spectrometric analysis. The fluid channels (12) may be formed onto a channel plate that are in fluid communication with corresponding reservoirs. The electrospray tip (15) can be formed along a defined distal portion of the channel plate that can include a single or multiple tapered surfaces. The fluid channels (12) may terminate at an open-tip region (18) of the electrospray tip (15). A covering plate (5) may substantially enclose most portions of the fluid channels (12) formed on the channel plate except for the open-tip region (18). Another aspect of the invention provides methods for conducting mass spectrometric analysis of multiple samples flowing through individual fluid channels (12) in a single microfluidic chip (10) that is formed with a tapered electrospray tip (14) having an open-tip region (18).
